Question

Identify a process in a bank and one in a retail store that control charts can be used to monitor.

Answer #1

**Identify a process in a bank and one in a retail store
that control charts can be used to monitor.**

A bank process which may be controlled using a control chart (one of the below):

- The no. of customers waiting to be served

- The no. of erroneous transactions per day A retail store (e.g., a grocery store) process which may be controlled using a control chart (one of the below):

- The no. of items with different shelf and register prices per day

- The amount of dollars short per cashier-shift

- The number of shoplifting per week

- The dollar amount of spoilt groceries thrown out per day

What are the different types of control charts that are
available to monitor a process?

Aspen Plastics produces plastic bottles to customer order. To
monitor the
process, statistical process control charts are used. The central
line of the chart for
the sample means is set at 8.50 and the range at 0.31in. Assume
that the sample
size is 6 and the specification for the bottle neck diameter is
8.50 ± 0.25.
a. Calculate the control limits for the mean and range charts. (3
points)
b. Suppose that the standard deviation of the process distribution
is...

Broody Plastics produces plastic bottles for the customer
orders. Statistical process control charts is being used to monitor
all the process. assume that the sample size is 4 and the
specification for the bottle neck diameter is 6.00+-0.35.
(Note that the central line of chart for the sample means is set
at 6.00 and the range at 0.4 in.)
(a) Calculate control limits for the mean and range charts.
(b) If the firm is looking for the three-sigma performance, is...

We use statistical process control charts to get a better handle
on the variation in our data. These tools make the process
performance visible; determine if the improvement is significant;
and determine if the improvement is maintained over time. For this
assignment, we will explore a run chart. Discuss what a run chart
is. What type of data can be used with this tool? What are the
steps used to analyze a run chart? Identify and discuss the four
run...

Using Control Charts for Improving Healthcare Quality
The National Health Service (NHS) in the United Kingdom makes
extensive use of SPC charts to improve service delivery to
patients. SPC charts are frequently developed using Excel
spreadsheets. Employees throughout NHS attend a two-day training
course where they learn about X- and R-charts and their
application. They also learn about Deming’s 14 points and
principles of quality management and how to improve processes in
their own operation. The number of possible applications...

Control charts for x bar and R with subgroup size=4
are used to monitor a normally distributed quality characteristic.
The control charts parameter were: X bar chart UCL=813, x bar chart
CL=800, x bar chart LCL=787. R chart UCL=46.98, R chart CL=20.59, R
chart LCL=0, both charts exhibit control. If the process mean shift
from 800 to 780. What is the probability of detecting this shift on
or before the second sample?
A.
0.9934
B.
0.9834
C.
0.9993
D.
0.9894...

This is for retail store perspective.
The control types could include feedforward controls, concurrent
controls and feedback controls Groups should be careful to be
specific in identifying the items to control. One item can have
more than one type of control.

Process in statistical control has a mean of 100.0 and standard
deviation of 3.0. ?_bar and ? charts with subgroups of size 7 are
used to monitor the process. If the process center shifts downward
to 96.0, what is the probability of first point falling outside
?_bar chart control limits is on the third sample taken after the
shift?

Discuss the Process that can be used by Management to
effectively identify, mitigate, track, and control business risks,
particularly those that could result in the financial statements
being materially misstated.

Honda uses statistical process control to monitor and improve a
variety of processes. Employees collect data, and then analyze it
using statistical process control charts. They can make adjustments
if needed. The statistical process control charts enable workers to
understand precisely how processes are working and anticipate
problems before they occur. One interesting use is in monitoring
the effort required to close a door. Honda monitors the speed of
the door required to make it latch by using a special...
